How we handle glazing silicone in Upper Green
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. Common call-outs are for split or lifting silicone on glass and water tracking down the inner face of the glass, across shower screens, glass-to-frame joints and glass balustrade bases.
In a village or hamlet like Upper Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes as standard.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep air moving in the conservatory
- Don’t use a blade near the sealant
- Inspect the sealant on glazing annually
- Clean glass with a mild cleaner and a soft cloth
Avoid scraping near the new silicone when you clean. A soft cloth or sponge is best.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with straight away.
What affects the cost of glazing silicone
We don’t publish a price list, because jobs vary so much. What we look at:
- The type of sealant required
- The old material and how stubborn it is
- Working hours on commercial sites
- Whether the work is at height
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.
Asking for a quote
What to tell us when you ask for a quote:
- Where the property is
- How we’d reach the joints
- The rough size of the job
- If someone has resealed it before
To get a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
When to call us in Upper Green
Not every leak is a sealant problem: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.
Signs it’s time to call us include:
- Conservatory leaks at frame and glazing joints
- Drips on the inside of a conservatory window
- Failed sealant around rooflight glass
- Glass-to-glass joints that have split
Letting a property close to Kintbury station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
What to look for in a quote
- How the colour is chosen
- Whether VAT is included
- When the joint can take water or movement
- Whether they seal over old material or remove it

Advice
Glazing silicone in Upper Green: local notes
With historic houses such as Stargroves (about 2.9 miles south-east) nearby, there’s older building stock in the area around Upper Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Michael include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Inkpen Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
Shower screens
Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
